About a month after getting the truck, the seemingly original radiator began leaking. I took it into a local radiator shop and they were not able to repair it. So, I sourced an aluminum radiator and built an aluminum shroud for it that would allow use of an electric fan. I added an electric fan, relay and a Derale electric fan controller. I also added a timed switch, so the fan comes on once the engine is warmed up (at thermostat housing) and shuts off when the engine temp falls below 180°, or will run up to 5 minutes after the engine is shut down, whichever comes first.
